Had a 72k dealer service yesterday and they advised me to get the rear discs and pads changed due to corrosion (I had noticed rust particularly at the centre and around the rims). The fronts are ok. They quoted me £260 to replace.

3 years ago (or to be more precise in January 2008) all the discs were replaced under warranty, also due to corrosion, and here we go again, two replacements in a 5 year old car. Is this a common problem or is it just me that seems to suffer from premature disc failure? The car is garaged every night and I can't think of any unusual circumstances that would contribute to it.

I have asked the dealer to query it with Honda UK and whether or not I would still be covered under warranty for the replacement cost (they couldn't tell me the warranty period for the replacement discs). Sods law says it will be 3 years

 

Common problem on just about any vehicle; brake discs are cast iron (most of the time) and almost certainly dont come with any coatings to help against corrosion.

Do yourself a favour next time you have a need to take your wheels off, get some high temp hammerite paint and brush around the bells and around the rim/edge of the disc. increases the aesthetics (no more horrible rust showing) and will also protect against corrosion!

You will probably think that you shouldn't really have to do this however, it will save you the hassle in the future!!

Alternatively, next time you need discs find some 2 piece ones with ally bells.

 

Think yourself lucky you don't own a Boxster, horredenous for this and very high disc replacement costs.

Dealers tend to say your discs need replacing prematurely, it's a nice earner for them.

Buy some replacements at a much lower cost from here http://brakeparts.co.uk/

Try braking a bit harder more often in future, that'll help.

Perversely garaging can make the problem worse, as a garaged car will dry more slowly and thus the brake discs are more likely to corrode.

 

The dealer tells me this every time I have a service. The first time I got worried and did what they said only for them to corrode again pretty much straight away.

If you are just talking about surface corroson (which I presume you are) then it doesn't make any difference. Go for a quick flog round the block and hey presto! The rust is gone. Leave the car in the rain overnight and it's back.

ps. I am not a brake expert or mechanich or anything so anything I say is to be ignored of course.

 

Oh, and also the dealer recommends the pads are changed as well as they have been worn down the mythical "70%". When I had a look there was a massive chunk of pad left.

edit: pps. There is no warranty on discs other than for a manufacturing fault (as far as I know), as they are classed as a consumable

 

Also have rust rear discs

When I get them replaced I'll hammerite as suggested. As long as its just surface corrosion and not compramising the disc I wouldn't be too worried.

 

I agree with ' lovegroova '

always replace pads with discs....

 

My oem discs rust over within an hour of washing the car. So I always have a bit of a drive afterwards to clean off the rust and get a bit of heat into things so any dampness dries out. The car is left garaged most of the week so I always leave the handbrake off while garaged to stop the discs rusting where the pads contact.

 

If they are not below minimum thickness WTF! People pay good money for discs with holes and groves in them, what difference is a few rust pits going to make? I think your stealer is taking the piss.
